Enterprise Agentic RAG

A self-correcting CRAG-style document Q&A system with conditional routing, quality gates, bounded retries, web fallback, privacy controls, and fully local execution.

Self-correcting retrieval

Document relevance, answer grounding, and usefulness gates control the generation loop; failed checks trigger corrective regeneration, query rewriting, or web fallback.

Model routing & benchmark harness

Task-level model routing cut measured inference cost by 84.5% while improving benchmark pass rate from 98.3% to 100% (180/180). A protocol-driven benchmark harness adds frozen inputs, fresh-process isolation, observation-level model identity / usage / cost audits, and quality-first decision gates.

Privacy & reliability boundaries

Per-run LLM/web budgets, secret redaction, prompt-injection hardening, metadata-only observability, graceful degradation, Privacy Mode, and Fully Local Ollama mode.

ENTERPRISE AGENT ARCHITECTURE

Enterprise Office Agent

A deterministic-first agent layer that routes free-text requests across seven enterprise workflows, using LLMs only where language synthesis adds value.

Knowledge Q&AEmail SummaryCalendar Lookup Ticket AssistantDaily BriefingMeeting PrepWorkflow Approval

Deterministic-first routing

Core office workflows remain reproducible and offline-capable by default; Knowledge Q&A delegates to the RAG engine through a thin adapter.

Controlled LLM action surface

Email Summary and Daily Briefing can use bounded LLM assists, but the model cannot send email, approve workflows, or mutate business data.

Observable & testable

The workspace exposes execution paths, timings, run settings, counters, and privacy state. Validation recorded 350 Office Agent tests and 1,103 repository-wide tests.

MULTI-AGENT AUTOMATION · SAAS INTEGRATION

Business Development & RevOps Automation

A Manager–Worker workflow that turns requirements documents into prospect research, CRM records, and personalized outreach drafts while preserving human review before sending.

Requirements PDFManager AgentProspecting RevOps+SDRCRM + Gmail Drafts

Manager–Worker orchestration

A Business Development Manager parses ICP / requirements PDFs, invokes Prospecting once, then fans out RevOps and SDR sub-agents independently per prospect.

Real SaaS integrations

Firecrawl and Hunter support company/contact research and work-email discovery; Pipedrive creates Organizations, Persons, and Leads; Gmail creates personalized drafts.

Explicit data contracts

Structured Output, subworkflow input schemas, conditional branching, and isolated side-effecting steps separate LLM reasoning from CRM writes and draft creation.

COMMERCIAL ENGINEERING EXPERIENCE

Full-Stack Engineering · Dental SaaS

Full-Stack SaaS Development

Sole full-stack engineer for a dental SaaS application, responsible for product design, system architecture, frontend and backend development, debugging, maintenance, and iterative feature delivery.

Cost-focused redesign

Redesigned a mobile dental-scanning workstation to improve portability and simplify the system architecture, reducing related hardware costs by approximately 50%.

Business impact

Delivered tens of thousands of dollars in confirmed savings during the initial rollout, with additional six-figure projected savings at full scale.

AI-NATIVE ENGINEERING WORKFLOW

Architecture-first, AI-assisted development

Coding agents are used for rapid codebase onboarding, architecture mapping, implementation, review, and validation — with task-based model selection and cost-aware workflows.

01Scan codebase & build architecture map
02Identify critical execution paths
03Write spec & constrain implementation
04Review diffs, tests, and system boundaries
05Use stronger models only where complexity justifies cost
